Which of the following correctly describes the strengths of the acids in solution?

HA is an example of a strong acid, HB is an example of a weak acid.

HA and HB are both examples of strong acids.

HA and HB are both examples of weak acids.

HA is an example of a weak acid, HB is an example of a strong acid.

Use the K a values to determine whether there are more products or reactants at equilibrium for the given reaction. K a NH 4 +1 = 5.6x10 -10 K a HCO 3 -1 = 4.8x10 -11

More products. K a NH 4 +1 > K a HCO 3 -1

More products. K a NH 4 +1 < K a HCO 3 -1

More reactants. K a NH 4 +1 > K a HCO 3 -1

More reactants. K a NH 4 +1 < K a HCO 3 -1

A sample of pure water is neutral because it contains

equal amounts of hydroxide and hydrogen ions.

A student titrates 20.0 mL of 1.0 M NaOH with 2.0 M formic acid (weak monoprotic acid). Ka=1.8 x 10 -4 . What is the solution at the equivalence point?

basic, the only ion present at equilbrium is the conjugate base

acidic, the strong acid dissociates more than the weak base

basic, the higher concentration of the base is the determining factor.

neutral, equal moles of both acid and base are present

If the formic acid were replaced by a strong acid like HCl at the same concentration, how would that affect the volume needed to reach equivalence point?

changing the strength of the acid will not change the volume needed to reach equivalence pt.

the change would reduce the amount because the acid fully dissociates

the change would reduce the amount because the base is now more strongly attracted to the acid

the change would increase the amount because reaction will go to completion instead of equilibrium
